Merge tag 'driver-core-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core 

Pull driver core updates from Greg KH:
 "Here's the driver-core / kobject / lz4 tree update for 4.1-rc1.

  Everything here has been in linux-next for a while with no reported
  issues.  It's mostly just coding style cleanups, with other minor
  changes in here as well, nothing big"
